Amsterdam's Foam is hosting a spectacular Diane Arbus exhibition. The entire gallery space is devoted to her work, with room after room of Diane's singular take on human experience providing an oddly warming experience. Her 'this is how it is' photographs have lost nothing of their power since her death forty years ago, and Foam have done well to keep the installation traditional, verging on austere. It's a terrific show, one of my favourites of the year. If you're in Amsterdam before January 2013, then it's well worth the entrance fee. If I were a rich man, I'd buy the catalogue.
